FERDINAND KLEEMANN, OF OBEBTFBKHEIM, VVI JRTEMBEBG, GERMANY.

APPARATUS FOR CLEANING KNIVES AND FORKS.

SPECIFICATION forming part of Letters Patent No. 392,870, dated November 13, 1888.

Application filed November 29, 1887. Serial No. 256,378. (No model.) Patented in Germany February 3, 1886, No. 36,164, and in Austria-Hungary March 24, 1888, No. 43,975.

To all whom it may concern.-

Be it known that I, FERDINAND KLEEMANN, of Obertiirkheim, Wiirtemberg, Germany, have invented certain new and useful Improvements in Apparatus for Cleaning Knives and Forks, (for which Letters Patent heretofore were granted to me by the governments of Germany, dated February 3, 1886, No. 36,164., and Austria-Hungary, dated March 24, 1888, No. 43,975,) of which the following is a specification.

The object of my invention is to provide a new and improved device for thoroughly polishing knives and forks easily and rapidly and without any waste of polishing-powder.

The invention consists in the combination, with a recessed standard, ofpolishing-blocks in the same, a funnel for conducting polishingpowder to a bore in the adjacent faces of the blocks, and springs acting on the blocks.

The invention also consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a face view of my improved apparatus for polishing knives and forks. Fig. 2 is a vertical transverse sectional view of the same. Fig. 3 is a sectional plan view showing the knife passed through the apparatus.

Similar letters of reference indicate corresponding parts.

The saucer A is provided with the standard B on its upper surface and the hook O on its under side, said hook being provided with the screw D for clamping or holding the device on a table. The standard B is provided with the recess E, in which are placed two rubber polishing-blocks, F, resting on a rubber plate, G, on the bottom of the recess. A rubber top plate, H, is placed upon the tops of the rubber blocks F, and over the plate H the metal plate J is placed, which is fastened by screws upon the top of the standard B. A funnel, K, is formed on the center of the metal plate J, and is in communication with a bore, L, formed in the adjacent faces of the blocks F.

The standardBis provided on each side with a hollow lateral extension, N, each containing a spiral spring, P, bearing against a metal plate, 0, resting against the outer side of a rubber block, F. The outer ends of the springs 15 rest against screws Q, screwed through the closed outer ends of the lateral extension N, and serving to adjust the tension of the springs P. On the top of the extension N the plain and serrated rubber strips R and S are secured, which are to be used for polishing forks.

In place of the rubber, cork or leather may be used in the implement.

The edges of the blocks F are rounded off, as at a, to facilitate the entering of the knives. The polishing-powder is filled into the funnel K and the bore L. The blade of the knife is forced through the slit between the two blocks and through the column of polishing-powder in the bore L, and is moved forward and back, the blunt edge or back resting on the plate G. The particles of polishing-powder carried along by the blade are rubbed on the surfaces of the faces of the blocks F. The waste powder 001- lects in the saucer.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a device for polishing knives, the combination, with a recessed standard having hollow lateral extensions, of polishing-blocks in the recess of the standard, a vertical bore being formed in the adjacent faces of the blocks, a funnel at the upper end of the bore, springs in the lateral extensions exerting pressure against the polishing-blocks,and screws in the ends of the extensions for adjusting the tension of the springs, substantially as herein shown and described. 1

2. A device for polishing knives and forks, having a standard provided with a recess for receiving polishing-blocks,and with abradingstrips on said standard, substantially as herein shown and described.

In testimony that I claim theforegoing as my invention I have signed my name in presence of two subscribing witnesses.
